Looking to restore a little sense of wonder this weekend? Why not visit your nearest national park?

The United States is home to 59 officially designated National Parks, the approximate locations of which appear on the map below. Using the mathematical concept of Voronoi tesselation, reddit user wouj divided the map into sections that can help you determine which national park is closest, geographically, to your particular point of origin. In a nutshell, each "Voronoi region" contains a national park, along with every geographical point whose distance to that park is less than or equal to its distance to any other national park.

"I think Voronoi diagrams are already a pretty beautiful and interesting mathematical structure," wouj tells io9, "but beyond that, the question of which national park is closest to a given area seemed worth asking." People typically drive or roadtrip to national parks, wouj reasons, and a Voronoi diagram is a nice way to visualize the consideration of distance one might make when selecting a destination.
